SAFETY PRECAUTIONSAlways observe the following points before operating orinspecting a unit.DANGERAlways turn off the main power supply to the facilitybefore disconnecting the power plug.Always turn off the main power supply to the facilitybefore inspecting the interior of the control box.※This is important because high voltage remains at thecircuit breaker and the optionally provided modem eventhough the circuit breaker in the control box is turned off.Modem P–VHFUSEB5P-VHB3PSVHRAÅ H341TDCircuit breakerHigh voltage3

WARNINGDo not touch the condenser fan while power to theunit is ON.Before removing the condenser fan cover, turn off thecircuit breaker and disconnect the power plug.During air-cooled operation : Condenser fan may startand stop automatically forthe refrigerant highpressure control.During water-cooled operation: Condenser fan may startand stop automatically forcooling of the control box.4

CAUTIONBefore starting the unit, run the generator.Securely close the control box cover.Otherwise, it will allow water entry.Temperature Recorder (OPTION)Temperature recorder box coverControl box coverQuick-lock lever5

CAUTIONWash the refrigeration unit with fresh water at PTI.Carefully flush the air-cooled condenser with fresh water toremove the salt that sticks to it.6

CAUTIONRefrigerant and refrigerant oilBe sure to only charge the unit with refrigerant HFC 134a.Never attempt to use any other refrigerant (CFC12, HCF22, etc) with therefrigeration unit.If any other refrigerant not specified is charged, it may cause problems with the unit.Use only Daikin specified oil (IDEMITSU, Daphne Hermetic Oil FVC46D) whenreplacing the refrigerant oil.If any other refrigerating machine oil not specified is charged, it may cause problemswith the unit.DA P H N ES W -4 6F V C46 DOILHER M E TI C O I LDAPHNEHERMETIC OILFVC46DSUNISO3GS-DIOpen the oil can, just before charging the oil, and use all the oil in the can onceopened.Do not leave the can open for 5 hours or longer to avoid moisture entry.Using any refrigerant oil which has absorbed moisture may cause problems with theunit.MoistureMoistureUse only exclusive tools for HFC134a. (gauge manifold, charging cylinder, etc)Do not use any tools for CFC12 or HCFC22.Service ports with exclusive quick joints for HFC134a are provided in the refrigerationunit to avoid improper refrigerant or refrigerant oil from entering into the refrigerationcircuit. (Refer to section 4.1.2)The charging hose and gauge port are not interchangeable with those of previousmodels using other refrigerants.7

1.3 BASIC OPERATION OFREFRIGERATION UNITw1.3.1 Starting operation(1) Connect the power plug to the power supply.Insert the plug q suited to the power sourcevoltage, and fasten the plug firmly.(2) Turn on the main power switch of the powersource facility (outside the unit)(3) Turn on the circuit breaker w.Liquid moistureindicator(4) Close the control box cover fully.If it is poorly closed, it will allow water entry.Check the contact around the packing, andfirmly close the cover. (Refer to the"CAUTION " on page 5.)1(5) Press the UNIT ON/OFF key e.e1-2

1.3.2 Checking during operationChecking items(precautions)Method of check1. Check the compressor, fan, pipes, etc. for abnormal noise and vibration. Visual and auditoryVisual2. Check the refrigerant for shortage.During the chilled mode, the bubbles alwaysappear in the moisture indicator.Do not charge the refrigerant excessively.Overcharging can damage the compressor.Visual3. Check the refrigerant for moisture inclusion.The moisture indicator colour;Green: normalYellow: abnormal.Visual4. Check operating conditions with the pilot lamps.Liquid moisture indicatorqPower plugw1.3.3 Procedure after operation(1) Turn off the UNIT ON/OFF key e, and turn offthe circuit breaker w.(2) Close the control box cover tightly.(3) Stow the power cable.Disconnect the power plug q, and stow thepower cable directing the plug openingdownward to prevent sea water or rain waterfrom collecting in the power plug.qe1-3

1.3.4 Adjust the ventilationAdjust the opening of the ventilation !0according to the cargo.CAUTIONKeep the ventilation closed duringtransportation of the frozen cargo.When ventilation is not required set the handleto "CLOSE".When ventilation is required (chilled mode),slide the handle upward.※Set the arrow mark of the ventilation at thegraduation on the scale to adjust theventilation as desired according to the cargo."CLOSE"Air inlet"OPEN"Ventilation coverNameplateAir inletHandleAir outletAir outlet1-4
